WILLIAM E. APPLEBY,`.OF VINDSOR, ONTARIO, CANADA.

kToaZZ whom t may concern i Be it known that I, WILLIAM H. ArrLnBi'-,

a' subject of the King of England, residing at Windsor, in the county of jEsseX and Province of Ontario, Canada, have invented certain new and useful Improvements in Door-Latch Devices, of lwhich the follow ing is a specification, reference 'being had therein to the accompanying drawings.

My invention aims tofprovide 'al lock or latch device that may be advantageously used in connection with the door ofy an automobile or'other vehicle,the latch device having provision so that it may be operated from the upper edge of a door ory at either side thereof, and thev device is particularly characterized by the few parts or simplicity of construction entering into the vlatch device.A l

'1t isin this connection, that ,the lock or latchcasing is madeof asinglepiece of material cut and lbent to provide an inclosure having a rlatch guide yand spring housing, and in the simple form of my invention there is only a pivoted` lever besides the latch, spring and casing. lWiththese few parts the lock or latch device can .be easily and quickly assembled and asl readily installed, while in other forms of my invenvtion handles or knobs' are provided so ythat the lock or latch devicei'may be operated fromeither side of ay door or other 'closure member. v p l i My invention in its various forms will be hereinafter' considered and then claimed, andreference will now be had to the drawings, wherein l Figure 1 is a side `elevationfof thelock or latch device, partly broken 'away and partly in section; t

Fig. 2 is a horizontal sectional view of the same in connection with a door jamb and door frame;

Fig. 3 is a vertical cross sectional view of the lock casing;

Fig. 4 is a perspective view of the same;

Fig. 5 is a perspective view of a detached latch;

Fig. 6 is a vertical cross sectional view of a lock or latch device provided with an outside or single handle;

Fig. '2'k is a side elevation ofthe same;

y latch guide andspring housing.

F ig." 8 is a vertical cross sectionalview ofthe lock 'or 1 latch device showing 'the same equipped with two handles, and

F ig. 9 is a plan or 'developed view. of a casmg'blank. y

` As' setv forth in the beginningthelatch or lock casing is made from asingle piece rof material as sheet metal, cut or stamped to provide a blank substantially as shown in* Fig. '9 and the blank is substantially rectangular in .plan with two'side extensions.

'lhe greater part of the blank provides va side wall 1 having openings 2 adapted to receive screws or other fastening means so thatthe side wall of thecasing may be. connected to a door frame 3 recess 4 or cutaway portion ofv saidframe. -One ofthe'extensions of thefblank is at aside edge of the wall landwhen bent on thek dash lines 5 at a `right angle to the wallfls'aid' extension provides anv end wall 6 having openings 7 for screwsv or other yfasteninomeans vemployed for k connecting the yend wall ytoxthe edofe of the door frame 3.

` nother portion of theblank 1 is adapted to be bent on the parallel dash lines 11`to provide walls 8, 9 and 10 adapted to cooperate with theside wall 1in providing a y The walls 1,v 8, 9 vand ',lprovide a klatc guide rand spring housing approximately the* same length. as ,the side 'wall' `land;rectangular in cross section, said guide and housino' beine" yformed at tlieupper edge of the side wav1 and adapted' to'fiitin `a groove K 14 provided thereforin the'door framei.v` Y

' The walls Sand 9 have lugs 13 atone end thereof adapted to be bent onthe dash lines 12 at a right" angle ,to said ywall and thus form an end labutment or end wall for one end of a coiled spring 15'. f

At the opposite'end of the spring housing the wall 8 has an apertured lug 16 that is bent upwardly on the dash line 17 at right angles to said wall, so that it may cooperate with the end wall 6 in holding the casing relative to the door frame 3. y

Slidable within the guide and s ring housing is alatch 18 that is rectangu ar in cross section and prevented from turning by the walls of the housing. rlhe outer end of the latch is beveled as at 19, and adapted tol Specification ofetters Patent. .Paented AugQQg, 1922. sppkn'qatinfiedaanuary 19,1920. `serian No. 352,520.

the spring undercompression when the latch is retracted.

Pivotally connected to the side wall l,l adjacent the lower edge thereof, by a rivet 23 Orother pivotal means, is the lower end of an operating lever 24, and said lever extends through slots 25 and 26 of the walls 8 and 10l respectively and engages in a notch 27 providedl therefor in the side wall of the latch 18. The lever 24 is offset, as best shown in Fig. l, and the upper end thereof terminates in a handle 28 which protrudes above the door frame convenientfor manipulation so that said lever may be oscillated to retract the latch 18 and released to permit of the expansive force or' the spring l5 distending the latch for engagement with the door j amb keeper 20, As shown in Figs. 2and 3 the lever 24 extends upwardly at the inner side of the side wall land is held against displacement by the latch and vits guide.` Thelever is normally held against end walls of 'the slots 25 and 26 by the expansive` force of thespring 15, and when vclosing. the door there is. sufficient clearance inthe notch 27. of the latch toV permit of the latch being partially retracted by the keeper ,20' before the lever 24 is engaged. This permits of the latchgaining sufficient impetus? A to shift the lever 24 and permit .of lthe door being completely closed, before the lever assumesa normal verticalpositionas shown in Figi. c n

Sometimes it is desirable to use inner and outer handles or knobs for the lock or latch device,1and,by reference to Figs. `6 and 7,

it willbe observed Athat the door frame 3 is provided with a rotatable spindlehaving a .tang 3OfL extending linto an opening provided ,therefor in the lower offset end of a leverj3l.

The lower end ofthe lever 32 is slotted and loosely supported by. a rivet 3l and this rivet is simply employed to hold the lever against accidental displacement, when the spindle 29. is withdrawn. yThe outer end of the spindle 29has a conventional form of .handle l32` with the base of the handle rotatable in a socket or escutcheon plate 33 on the outer side of the door frame, and a detachable collar 34 on the spindle 29 prevents such spindle and its handle 'from becoming accidentally displaced relative to the socket plate 33..

When door knobs or handles are to be used, as shown in Fig. 8, it is not necessary to use a long lever for engagement with the latch, but simply a short lever orv arm 35. it is also unnecessary to use the collar 34, as a handle or knob 36 may be mounted on the inner end of a spindle 37 which is of oreater length than the spindle 29, the spin- 2die and its handles or knobs permitting of the lever or arm 35 being oscillated to retract the latch oi' the lock.

llt is thoughtthat the operation and utility of the latch device will be" apparent without further description, and while in the drawings, there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such changes as fall within the scope of the appended claim; c

What I claim is i A door latch device made from ablank cut toprovde a side wall, anend wall, a lug, and walls' which are bent to form a housing longitudinally of the upper'edge 'of said side wall, said housing walls having bent portions affording an end abutment, said housing .walls having lever slots, a lever extending throughy the lever slots against said side wall, a spring in said housing against the end abutment thereof, a latch slidable insaid/housing and having a notch through which said lever extends, said latch having a conical end extending into an end of said spring, a handle spindle extending through said side wall and adapted for oscillating said lever to shift saidlatch in said.

housing, and a handle on each end'of the spindle so that the latch may be operated irom either side of the door.

In testimony whereof I aiiix my signature in the presence of two witnesses.

WILLIAM H.' APPLEBY.
